I tried it with the 3 seconds test avi from the site. It is
SLOW. It really kills the noise. The details... well, some are kept intact some are blurred. Watching the cleaned clip, I noticed that the blurred parts are kind of "moving" like the moving backgrounds in some avi codecs. It seems it is only a spatial denoiser, no temporal denoising (well that would make it even slower
).
My first impression is that it's not a denoiser for everyday use like backing up clean dvds or reasonably clean captures, but it can be handy if you've got a very problematic capture of something important enough to make the time you'll expend worth.
Thanks Boulder, I'll look at the FFT3D filter. Does it have a way to automatically build the noise "profile"? Does the 3D in the name imply it filters in the time axis too?
